Css Heroku应用程序即使在预编译后也未正确格式化

我刚刚创建了一个带有特定css样式的个人网站。在线消息来源称，在遵循这些指示后，我的heroku应用程序仍然没有正确格式化，所以在部署之前就已经对我的资产进行了预编译

有什么见解吗

我的文件如下所示：

    source 'https://rubygems.org'

    # Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
     gem 'rails', '4.2.1'
    # Use sqlite3 as the database for Active Record
     gem 'pg'

     gem 'rails_12factor'

     group :development, :test do
       gem 'sqlite3'
     end

    # Use SCSS for stylesheets
      gem 'sass-rails', '~> 5.0'
    # Use Uglifier as compressor for JavaScript assets
      gem 'uglifier', '>= 1.3.0'
    # Use CoffeeScript for .coffee assets and views
      gem 'coffee-rails', '~> 4.1.0'
    # See https://github.com/rails/execjs#readme for more supported runtimes
      gem 'jquery-rails'

      gem 'turbolinks'
    # Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
      gem 'jquery-turbolinks'

      gem 'jbuilder', '~> 2.0'
   # bundle exec rake doc:rails generates the API under doc/api.
      gem 'sdoc', '~> 0.4.0', group: :doc
      gem 'json'

   # Use ActiveModel has_secure_password
   # gem 'bcrypt', '~> 3.1.7'

   # Use Unicorn as the app server
   # gem 'unicorn'

   # Use Capistrano for deployment
   # gem 'capistrano-rails', group: :development

   group :development, :test do
   # Call 'byebug' anywhere in the code to stop execution and get a    debugger console
   gem 'byebug'

   # Access an IRB console on exception pages or by using <%= console %> in views
   gem 'web-console', '~> 2.0'

   # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
   gem 'spring'
    end

什么格式元素不正确？该网站是否是实时的，以便我们可以查看？是否有关于其外观的参考资料？如果“格式不正确”表示您的样式不存在，则应包括application.css的内容以及资产/样式表文件夹的文件结构。谢谢，是的，我的意思是“样式不存在”。我刚刚包括了application.css的内容

     default: &default
     adapter: postgresql
     pool: 5

     <<: *default

       production:
               <<: *default
         database: db/production

      * This is a manifest file that'll be compiled into     application.css, which will include all the files
      * listed below.
      *
      * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
      * or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
      *
      * You're free to add application-wide styles to this file and they'll appear at the bottom of the
      * compiled file so the styles you add here take precedence over styles defined in any styles
      * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
